OBJECTIVES: This study evaluated the expression profile of the mesothelin ( MSLN) gene and its prognostic significance in breast cancer. METHODS: To evaluate the diagnostic and prognostic significance of mesothelin, immunohistochemistry was used to assess the level of mesothelin protein in surgically resected, formalin-fixed, paraffin-embedded invasive breast carcinoma specimens. Associations between mesothelin and other biomarkers, including oestrogen receptor (OR), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2/neu), were also evaluated. RESULTS: A total of 182 breast carcinoma specimens were included. Mesothelin protein was present in the membrane of malignant cells. There was correlation between the presence of mesothelin in tumour cells and tumour infiltration of the lymph node. There was no correlation between the presence of mesothelin and HER2/neu protein, OR and PR in tumour cells. Mesothelin levels were significantly associated with decreased overall survival. CONCLUSIONS: Lymph node status, tumour size, HER2/neu and mesothelin protein levels in breast cancer cells were independent prognostic factors. Mesothelin could be useful as a prognostic marker of overall survival in invasive breast cancer.

PURPOSE: To assess the frequency of expression and the prognostic significance of a hypoxia-regulated marker, carbonic anhydrase IX (CA IX), in a cohort of patients with invasive breast cancer. PATIENTS AND METHODS: CA IX expression was evaluated by immunohistochemistry with a murine monoclonal antibody, M75, in a series of 103 women treated surgically for invasive breast cancer. The majority of patients were treated with adjuvant hormonal or chemotherapy. The frequency of CA IX expression, its association with recognized prognostic factors, and the relationship with outcome was evaluated by univariate and multivariate statistical analyses. RESULTS: CA IX expression was present in 49 (48%) of 103 cases. The level of CA IX expression was found to be significantly associated with tumor necrosis (P < .001), higher grade (P = .02), and negative estrogen receptor status (P < .001). Furthermore, CA IX expression was associated with a higher relapse rate (P = .004) and a worse overall survival (P = .001). By multivariate analysis, CA IX was also shown to be an independent predictive factor for overall survival (hazard ratio, 2.61; 95% confidence interval, 1.01 to 6.75, P = .05). CONCLUSION: CA IX expression was associated with worse relapse-free survival and overall survival in an unselected cohort of patients with invasive breast carcinoma. The potential role of CA IX as a marker of hypoxia within breast carcinomas was also indicated by a significant association with necrosis. Further work assessing its prognostic significance in breast cancer is warranted, particularly interactions with radiotherapy and chemotherapy resistance.

Abstract Background Women with screen-detected invasive breast cancer who have macrometastatic disease on axillary sentinel lymph node biopsy (SLNB) are usually offered either surgical axillary node clearance (ANC) or axillary radiotherapy. These treatments can lead to significant complications for patients. The aim of this study was to identify a group of patients who may not require completion ANC. Methods Data from the NHS Breast Screening Programme between 1 April 2012 and 31 March 2017 were interrogated to identify women with invasive breast carcinoma and a single sentinel lymph node (SLN) with macrometastatic disease who subsequently proceeded to completion ANC. Univariable and multivariable analyses were performed to identify patients with a single positive SLN who had no further lymph node metastasis on ANC. Results Of the 2401 women included in the cohort, the presence of non-sentinel node disease was significantly affected by: the number of nodes obtained at SLNB (odds ratio (OR) 0.49 for retrieval of more than 1 node), invasive size of tumour (OR 1.63 for size greater than 20 mm), surgical treatment (OR 1.34 for mastectomy), human epidermal growth factor receptor (HER) 2 status (OR 0.71 for HER2 positivity), and patient age (OR 1.10 for age less than 50 years; OR 1.46 for age greater than 70 years). Patients aged less than 70 years, with tumour size smaller than 2 cm, more than one node retrieved on SLNB, and who had breast-conserving surgery had a lower chance of positive non-sentinel nodes on completion ANC compared with other patients. Conclusion This study, of a purely screen-detected breast cancer cohort, identified a subset of patients who may be spared completion ANC in the event of a single axillary SLN with macrometastasis.

Extracellular Matrix Components

CAFs (cancer-associated fibroblasts), the most abundant cell type in breast cancer stroma, produce a plethora of chemokines, growth factors and ECM (extracellular matrix) proteins, that may contribute to dissemination and metastasis. Axillary nodes are the first metastatic site in breast cancer; however, to the present date, there is no consensus of which specific proteins, synthesized by CAFs, might be related with lymph node involvement. The purpose of this study was to perform a systematic review of CAF biomarkers associated with the presence of regional metastasis. PubMed was searched using the words: ‘breast cancer’ and ‘lymph node’ and fibroblast or stroma or microenvironment. After exclusions, eight studies evaluating biomarkers immunoexpression in CAFs and lymph node status were selected. Biomarkers evaluated in these studies may be divided in two groups, according to their ontology: extracellular matrix components [MMP13 (matrix metalloproteinase 13), TIMP2 (tissue inhibitor of metalloproteinases-2), THBS1 (thrombospondin 1), LGALS1 (lectin, galactoside-binding, soluble, 1)] and response to wounding [PDPN (podoplanin), PLAU (plasminogen activator, urokinase), PLAUR (plasminogen activator, urokinase receptor), CAV1 (caveolin 1), THBS1, LGALS1]. A positive expression of MMP13 and LGALS1 in CAFs was associated with enhanced OR (odds ratio) for regional metastasis. Contrariwise, CAV1 positive staining of fibroblasts was associated with decreased OR for nodal involvement. Expression of MMP13, PDPN and CAV1 was further tested in a new series of 65 samples of invasive ductal breast carcinomas by immunohistochemistry and no association between biomarkers expression in CAFs and nodal status was found. It was suggested that breast cancer subtypes may differentially affect CAFs behaviour. It would be interesting to evaluate the prognostic significance of these biomarkers in CAFs from different tumour types.

Introduction: Tumor infiltrating lymphocytes (TILs) are widely considered a key sign of the immune interaction between host and tumor, and potentially prognostic biomarkers of good or bad outcome in various cancers, including invasive breast cancer (IBC). Aim and Objectives: To correlate the expression of CD4, CD8 T-lymphocytes in invasive carcinoma breast with established markers of prognosis like tumour size, grade, lymph node status and molecular subtypes mainly ER, PR, Her 2Neu, Ki67 status, mainly the triple negative breast cancers(TNBC). Methodology: 58 Invasive breast carcinoma proven tissue blocks were subjected to immunohistochemistry and morphometric analysis for positive CD4, CD8 T-lymphocytes were done. Results:  Triple negative breast cancer subtype shows high TILs than other pathologic subtypes. Tumor interface CD8+ cells very well correlated with the pathological higher nodal stage. Majority CD4, CD8 positive cells were populated more towards the stromal and interface of the tumor microenvironment rather thatintratumoral. Conclusion: CD4+ and CD8+ counts may be a valuable independent prognostic tool in predicting the outcome in invasive breast cancer.

Duodenal Adenocarcinoma

e15797 Background: Duodenal adenocarcinoma is a rare tumor representing approximately 0.3% of all gastrointestinal tract cancers. Prognostic factors in relation to survival outcomes for these patients are sporadically reported in the medical literature. We aimed to evaluate outcomes of patients with duodenal adenocarcinoma who underwent pancreaticojejunostomy treated at Mayo Clinic Rochester from January 1, 2006 to December 31, 2016. Methods: Clinicopathological data of 52 duodenal cancer patients were collected. JMP software was used for statistical analysis. Kaplan-Meier method and log-rank tests were used for survival analysis, and multivariate cox proportional hazards model was used to evaluate the prognostic effect of pertinent clinical variables. All tests were two sided and a P value of < 0.05 was considered significant. Results: The median age at diagnosis was 65.9 years (range 39-81). The median overall survival was 51 months (95% CI 31.3-105.4) and the median progression free survival was 30.4 months with median follow up of 73.4 months. There were 3, 9, 21, and 19 patients with stage I, II, III, and IV disease, respectively. Depth of tumor invasion (p = 0.0156) and lymph node metastasis (p = 0.0441) were associated with overall survival on multivariate analysis. Advanced clinical staging influenced overall survival in univariate analysis, but lost prognostic significance in multivariate analysis. Age, gender, surgical technique, presence of metastases, tumor size, number of lymph nodes removed, location of duodenal segment involvement, and adjuvant treatment had no significant impact on overall survival. Laparoscopic approach did not influence survival but was associated with less hospital days (p = 0.0437). Conclusions: Depth of tumor invasion and lymph node status were associated with improved overall survival in patients with duodenal adenocarcinoma. Laparoscopic procedure decreased the hospital stay without affecting outcomes.

Context Lymph node status and the number of lymph node (LN) positive for cancer cells are the most important prognostic factors in breast cancer. Extranodal tumor extension (ENTE) has been used as a histopathologic feature to classify patients into high risk versus low risk for local recurrence. However, in the current era of early detection and systemic therapy, the prognostic significance of ENTE is not as well defined in patients with 1 to 3 LNs positive for cancer. Objective To determine whether the amount of tumor burden in an axillary dissection or the presence of ENTE provides any additional information regarding patient outcome in patents with 1 to 3 positive LN results. Design Clinical and pathologic factors were identified for 456 patients with breast cancer at the University of Texas MD Anderson Cancer Center, Houston, who had pT1 tumors and 1 to 3 LNs positive for cancer and were treated by mastectomy, with or without postmastectomy radiotherapy, between 1978 and 2007. Results Of the 456 patients, 257 (56.4%), 141 (31.6%), and 58 (12.7%) patients had 1, 2, or 3 positive LN results, respectively. Extranodal tumor extension was present in 99 patients (21.7%) and was absent in the remaining 357 cases (78.3%). Seventy-six patients (16.7%) received radiation therapy. Patients had both worse overall survival time and disease-free survival when ENTE was present, regardless of the amount, as long as the treatment era was not included in the multivariate analysis (pre-2000 versus post-2000). However, ENTE was no longer significant on multivariate analysis when the year of treatment was taken into account. Conclusions The number of positive LNs remains an important predictor of survival in patients with 1 to 3 positive LN results, but the prognostic significance of ENTE in this cohort of patients has diminished over time.

OBJECTIVES: The effects of age at diagnosis on the clinical characteristics of breast cancer and trends over time were investigated in Chinese women. METHODS: Data from 4211 women with pathologically confirmed primary breast cancer collected between 1999 and 2008 for a multicentre retrospective study were analysed according to age at diagnosis. RESULTS: Age at diagnosis ranged from 21 to 86 years, with a mean of 48.7 years, and was shown to be significantly related to tumour size, lymph node status, hormone receptor status and human growth factor receptor-2 status, but not to pathological type or tumour, node, metastasis stage. The age-corrected proportion of patients aged 50 – 64 years at diagnosis increased significantly between 1999 and 2008. There was a significant difference in the age-corrected distribution of age at diagnosis in China compared with Western countries. CONCLUSIONS: Age at diagnosis is related to the clinical and pathological characteristics of breast cancer. The age at diagnosis in China increased over the decade from 1999 to 2008, but is still lower than in Western countries.

e22199 Background: Lymphangiogenesis plays an important role in cancer metastasis. Although animal models show a strong relationship between lymphangiogenesis and lymph node metastasis and survival, the clinical significance of lymphangiogenesis in colorectal cancer (CRC) remains uncertain. The goal of this study was to evaluate the association between c-Met and lymphangiogenic factors and to elucidate their prognostic significance for patients with CRC. Methods: A total of 379 tissue samples were obtained from surgically resected specimens from patients with CRC in Soonchunhyang University Cheonan Hospital between January 2002 and December 2010. The expressions of c-Met, vascular endothelial growth factor (VEGF)-C, VEGF-D, VEGF receptor (VEGFR)-3, and podoplanin were examined by immunohistochemistry. The expression of each marker and clinical factors were analyzed. Results: Three hundred and one of 379 (79.4%) tissues had c-Met expression. High expression of c-Met in tumor cells was significantly associated with high expression of VEGF-C (P < .001) and VEGFR-3 (P = .001). But, there was no statistically significant association with podoplanin (P = .587) and VEGF-D (P = .096). Of the 103 evaluable patients, expression of c-Met in tumor cells was significantly associated with advanced clinical stage (P = .020), positive lymph node status (P = .038), and high expression of VEGF-C (P = .020). But, there was no statistically significant association with podoplanin (P = .518), VEGFR-3 (P = .085), VEGF-D (P = .203), and overall survival (P = .360). Conclusions: Our results provide indirect evidence for an association and possible regulatory link of c-Met with the lymphangiogenic factors. But, c-Met expression in patients with CRC are not prognostic indicator for overall survival in this retrospective study.
